Feature: Add dead cards option for evaluation

[LukeLemes]

Dead cards option for evaluation in games Holdem, Omaha etc. Add to enable multi-board evaluation.

I wanted this feature also on cmdline ... do you thing we can merge this? ... It helps evaluate double board bomp pots

This can't be merged because it will break existing code. We need to add a wrapper that preserves the existing signature so that old code will still compile.
